Can't set Swift Combine Future Output Type to Void

In Swift Combine Future Publisher, I can’t set the output type value to Void

return Future<Void, Error> { (promise) in
promise(.success()) <— This line is in error

Missing argument for parameter #1 in call


I found it myself,

you need to call the promise this way, not really esthetic

Glad you found the solution to that.

You need the () because your Future is of type <Void, Error> if you change this, you will have to update the success param too.
